KNOTTED STITCH AND .'lVlIl'II-IODv OF MAK-ING- THE SAME.

1,esa,o11.

To all whom it may concern.' Y

Be it known that I, WILLIAM F. LAUTEN- scHLAGER, a citizen of the United States residing at Cincinnati, in the county of amilton and State of Ohio, have invented certain new' and useful Improvements in Knotted Stitches and Methods of Making the Same, of which the following is' a specification.

It is the object of my invention to provide a knotted stitch arranged to attach an object to fibrous or fabric material, which object may be instanced as a button, or as another or other fibrous or fabric piece or pieces of material, and which latter may be superposedA upon the first-named fabric or fibrous material to which it is attached or be arranged in edge to edge relation therewith.

My invention may be employed for securing a plurality of piecesof material'together in operations usually known as' rivetlng.. or tacking in the shoe and sewingindustriesj. or in reinforcing operations, in.l attaching shank-eye buttons in place, for instance, on' button shoes, in attaching flat buttons having eyes through the body of the button, for instance, inl attaching buttonsl to overalls, underwear, and for other purposes, for stapling the insoles of shoes to uppers, for tacking pieces together edgev to edge, as in the making of heel-lifts,.and for similar and other purposes.

It is the object of my invention to provide a novel knotted stitch, and method of making the same, and to provide a novel knotted stitch which is simple and readily formed and which will hold the objects together in close Contact and be so formed that the knot prevents loosening of the stitch, and further to provide the knot in such a position as to extend but slightly beyond the plane of the material.

It is a further object of my invention to provide a knotted stitch which is independent of other stitches, so that it may be employed in relations where it is desirable to form only a single stitch or but few stitches, arranged to hold two objects together in such manner as to avoid unraveling of the stitches.

rThe invention will be further readily understood from the following description and claims, and from the accompanying drawings.

Speccaton of Letters Patent.

Patented Nov. i2, i918.

Application filed October 26, 1914. Serial No. 868,654.

The knotted stitch may be formed manually or by machinery, as may be desired, although inthe ordinary course of manufacture the stitch will be more generally accomplished by suitable machinery or combination of devices acting on the thread. I have not herein shown any mechanism for manipulating the thread in accomplishing the desired results, as any mechanism suit-able for the purpose may be employed.

I have, in the drawings, illustrated various stages in the course of the formation of the knotted stitch, these stages being selective or arbitrary stages selected at points inthe formation of the knotted stitch which will most clearly show the manipulation of the thread, it being understood that, especially when the knotted stitch is formed by machinery, the o erations or mani aulations preferably take piface in a continuer and uninterrupted series of steps for forming the knotted stitch.

I have exemplified my invention as employed in securing together two superposed pieces of material; in attaching a shank-eye button to a piece of material; in attaching a flat button to a piece of material; and, in stapling two pieces together in edge to edge relation, from which the application of the knotted stitch in other relations will be readily perceived.

Fig. 21 is a similar view showing the primary loop flexed on the line of the stitch preparatory tol being received reversely through the other piece of material.

Fig. 22 is a similar view showing the primary loop received reversely through said other piece of material; and,

Fig. 23 is a similar view showing the knotted stitch attaching two pieces of material together in edge to edge relation.

Figs. l to 11 inclusive illustrate a riveting, tacking or stapling operation for securing together two superposed pieces of material designated at 11 and 12. It will be as'- sumed for convenience of description, that the stitch is being formed by suitable mechanism, in which the thread, designated generally as 13, is supplied from a suitable bobbin or spool, and that the stretch 14: of the thread is the supply stretch of the thread, and the stretch 15 of the thread is the initial stretch of the thread, which may be suitably initially held, as by a pair of jaws 16.

At the point where the stitch to be formed is located, the thread is passed through holes 17 and 18 in the superposed layers of material, suitably formed in the material either concurrently with or independently of the passing of the thread through the holes, depending on whether an eye-needle or a hook-needle is employed for the purpose. The thread is received through the holes for forming a primary loop 19, (see Fig. 1).

The primary loop is then deflected lengthwise of the line of the stitch as indicated at 20, (see Fig. 2). This may be accomplished either by feeding the material in the direction of the arrow or by defiecting the loop, the material remaining stationary, or by both these movements. The primary loop is received reversely through the material through the holes 21 and 22 in the superposed layers of material (see Fig. 3), distanced from the holes 17 and 18 a distance corresponding to the length of the stitch. The primary loop may be either pulled or pushed through the holes 21 and 22, depending on the instrument employed.

A supplemental loop 23 is formed in one of the stretches of the primary loop and is exemplified as formed in the supply stretch thereof. rThis supplemental loop is received through the primary loop (see Fig. 4f), and is preferably formed in great part by drawing upon the primary loop so as to cause the bight 24: of the primary loop to be drawn close about the primary stretch 25 and the secondary stretch 26 of the supplemental loop (see Fig. 5).

The other stretch of the primary loop, exemplified as the initial stretch 15 thereof, is received through the supplemental loop (see Figs. 6 and 7), tension being exerted upon the stretch so drawn through the supplemental loop and the secondary or supply stretch 26 of the supplemental loop for drawing upon the primary and supplemental loops, (see Fig. 8), and initiating the knot. A. pull, which is preferably a sudden and tense pull, is then exerted upon both ends of the thread of the stitch, exemplified as the primary stretch of the primary loop and the supply stretch of the supplemental loop, which exerts a tension upon the bight 2A- of the primary loop and upon the bight 27 of the supplemental loop for forming a bight 28 in the initial stretch of the primary loop, preferably drawing said bight partway into the bight of the primary loop and curving said last-named stretch about the biglit of the primary loop as shown by the hitch 29. The stretches of the supplemental loop are further preferably drawn in the form of bights 30, 31, partway into the hole 22, by the tension exerted upon the bight 24 in the primary loop, (see the knot as formed in Figs. 9, 10 and 11).

The stretches of the thread extending from the knotted stitch are then cut or snipped adjacent to the knot, as by the snippers 32, 33, leaving a slight length of thread however to prevent accidentally unraveling of the knotted stitch.

In Figs. 12 to 15 inclusive, I have illustrated the stitch employed for securing another material as a shank-eye button, in place. The stitch is formed in the same manner as that employed in attaching a plurality of superposed pieces of material together, as illustrated in Figs. 1 to 11 inclu` sive, the illustration of certain of the steps illustrated in Figs. 1 to 11 being omitted in Figs. 12 to 15, inclusive. Figs 12, 13 and 11, show the manner in which the shank-eye button is received about the primary loop and Fig. 15 shows the completed knotted stitch.

In these figures 111 represents the piece of material or shoe part. for instance the quarter of the shoe. to which the button 112 is arranged to be secured. The parts of the knotted` stitch in Figs. 12 to 15, inclusive are designated bv similar reference numerals employed for designating the knotted stitch parts shown in Figs. 1 to 11 inclusive but raised to the series 100. rIhe primary loop 119 is received through the shank-eye 118 of the button, which may be accomplished concurrently with the passage of the primary loop through the hole 117, or after the primary loop has been received through said hole.

In Figs. 16 to 19 inclusive my invention is illustrated as employed for attaching another material, as a pierced or flat button, to a piece of fabric, the piece of fabric being designated 211 and the flat button being desi gnated 212. The stitch and the parts thereof are similar to the stitch illustrated in Figs. 1 to 11 inclusive and are designated by similar reference numerals raised to the series 200. The fabric 211 may exemplify the trousers band of a pair of overalls, or the button fly of a piece of underwear or similar or other part.

In this exemplification the primary loop received through the hole 217 in the fabric, and through the hole 218 in the button, which may be accomplished concurrently with the passage of the primary loop through the hole 217 or after the primary loop has been received through said hole. The primary loop having received its deflection, as shown at 220. is received reversely through the hole 221 in the button and the hole 222 in the fabric, in manner n ed similar to the description with reference to the exemplification shown in Figs. 1 to 11, inclusive.

VrThe steps -employed for forming the knotted stitch exemplified in Figs. 1 to 11 are also employed in the exemplification illustrated in Figs. 1G to 19 inclusive, the illustration of certain of the steps being however omitted -in the latter figures, Figs. 16 to 18, inclusive showing the -means for receiving the primary loop through the button holes, and Fig. 19 showing the completed stitch.

In Figs. 20 to 23, inclusive, I have exemplified -my invention as employed in securing together two pieces of fibrous material or fabric in edge to edge relation, employed, for instance, in tacking together two pieces of scrap leather for forming intermediate lifts for the heels of boots and shoes. In this exemplification the pieces of material are exemplified at 311 and 312, the stitch and its parts being exemplified by reference numerals similar to the reference numerals employed in Figs. 1 to 11, inclusive, but raised to the series 300.

Illustration of certain of the steps employed in forming the knotted stitch is omitted in Figs. 2O to 23 inclusive, they being repetitions of the steps illustrated in Figs. 4: to 9, inclusive. Figs. 2O to 22 inclusive illustrate the stitch in its relation to the particular purpose illustrated in said figures, showing the primary loop 319 received through the hole 317 in the piece of material 311, deflected laterally across the proximate edges 33-1 of said strips, and received reversely through the hole 321 in the piece 312, the knotted stitch being formed for securing the said pieces in endwise relation as illustrated in Fig. 23.
